Title: Fluorescent x-ray film thickness meter
Inventor: TASHIRO HIROMI
IPC: G01N23/223
Filed: 1993-03-08
Abstract: PURPOSE:To allow the monitoring of sample image even during the measurement by providing a film thickness meter, having no mirror between a collimator and a sample, additionally with a frame memory thereby suppressing the spread ing of X-ray beam and the lowering of intensity thereof. CONSTITUTION:When measurement is not carried out, a sample image is inputted to a camera 1. An image signal from the camera 1 is stored in a frame memory 9 through an AD converter 8 and also delivered directly to a display 11. In this regard, a CPU 7 presents an signal from the camera 1 directly on the display 11 through a signal switch 12. When a sample is measured, the switch 12 is turned to deliver an image from the memory 9 to the display 11 and the collimator 5 is shifted onto the optical axis of primary X-ray thus starting measurement. Information stored in the memory 9 is a sample image immediately before starting measurement and since the sample 6 is not shifted intentionally, it can serve as a sample image monitor during measurement.

Filed: 1993-03-09
Abstract: PURPOSE:To facilitate cleaning without lowering cooking performance or usability, by a method wherein a moving table is positioned above a turning means, and the moving table can be separated from a turn table at a desired position. CONSTITUTION:When a door 2 is closed, a controller 9 operates so that weight of substance to be heated which is placed on a moving table 4 is detected by a weight detecting means 11, and based on weight information, both a heating means 3 and a turning means 7 are driven for heating and cooking. When the heating and cooking are finished and the door 2 is opened, a detecting means 8 detects an entire opening of the door 2 and then the controller 9 drives a driving means 5 to put the moving table 4 carrying the heated substance outward from the heating chamber 1. The moving table 4 and a turn table 12 are designed to be detachable from the heating chamber 1, and further a driving device 5 of a moving means 6 is arranged outside of the heating chamber 1. Thus, as the heating chamber 1 can be cleared up, cleaning becomes very easy.

IPC: H01L21/60
Filed: 1985-03-12
Abstract: PURPOSE:To prevent the generation of a short circuit of wire, cracks and the like of a chip caused by die-bonding by a method wherein a semiconductor element is placed on the bed of a lead frame through the intermediary of the anisotropic conductive sheet of the size almost the same as that of the bed, and the semiconductor element is sealed by resin. CONSTITUTION:A semiconductor chip 4 is placed on a bed 1 through the intermediary of an anisotropic conductive sheet 11 having a specific thickness. The size of the sheet 11 is to be almost equal to the size of the bed 1 for the purpose of preventing the connection of a wire 5 to the bed 1. Accordingly, the wire 5 does not come in contact with the bed 1 even when the wire is sagged as shown by the two-dot chain line 5' in the diagram. When a resin sealing is performed after completion of a wire bonding, the anisotropic conductive sheet 11 receives a strong pressure in vertical direction by the pressure of sealed resin, the sheet 11 begins to have conductivity in vertical direction, and the chip 4 and the bed 1 are brought into the conductive state. As a result, a short circuit generated by the wire 5 contacting to the bed 1 and the chip and the like caused by the non-uniformity of the thickness of the mounting material can be prevented.

Abstract: PURPOSE:To obviate the fluctuation of pressing power between two rollers which cooperate to deliver sheets of paper one by one so as to enable sheets of paper to be fed stably at all times, by providing means for transmitting power to one of said rollers in a direction normal to the direction of said pressing power. CONSTITUTION:A timing belt 35 for rotating a motor 11 clockwise is rotated in a direction B, and a pulley 30 is rotated clockwise. As a pulley 31 is rotated together with the pulley 30 in the same direction, a timing belt 36 is rotated in a direction C, and a pulley 32 and in turn a reverse roller 7 is rotated clockwise. In the case, the direction of the tension of the belt 36 is approximately in parallel to the line segment between shafts 8, 21. Thus when the position of the fulcrum shaft 21 is set in such a way that the line segment between the shafts 8, 21 is normal to the line segment between the shafts 8, 4, the force of the reverse roller 7 that will act on the feeding roller 7 can be nullified by the tension of the belt 36.
